Overview

EN IEC 60332-3-10:2018/A11:2020 specifies the apparatus, arrangement and calibration required for tests that assess vertical flame spread of vertically-mounted bunched wires or cables, including both electrical and optical fibre cables, under defined fire conditions. This amendment (A11) updates positioning and apparatus details used when performing the Part 3-10 vertical flame spread test within the EN IEC 60332 series. The standard is published by CLC/CENELEC and applies across member countries.

Key topics and technical requirements

• Scope: Apparatus and its calibration for the vertical flame-spread test of bunched (multi‑cable) vertical samples.
• Burner positioning (updated by A11):
  • Burner arranged horizontally at (75 ± 5) mm from the front surface of the cable sample.
  • Burner centreline located (600 ± 5) mm above the test chamber floor.
  • Burner symmetrical with the ladder axis and the flame applied between two rungs of the ladder.
• Apparatus layout: Specifies ladder support, rungs, wire ties and optional leg extensions for consistent sample mounting (Figure references updated).
• Calibration & arrangement: Defines repeatable set‑up and calibration routines for the burner and test chamber to ensure comparable, reproducible results across test laboratories.
• Standards management: Amendment details, implementation dates and CENELEC adoption obligations are included to support national standardization.

Applications and practical value

• Provides a repeatable laboratory method to characterize vertical flame spread behaviour of cable bundles, supporting:
  • Product development and material selection (insulation/jacket formulations).
  • Regulatory compliance and safety assessments for buildings, transport and industrial installations.
  • Comparison of cable designs and flame-retardant treatments under standardized conditions.
• Helps manufacturers and test laboratories generate defensible, comparable data used in safety reports, procurement specifications, and certification processes.

Who uses this standard

• Cable manufacturers (electrical and optical fibre)
• Independent fire test laboratories and certification bodies
• Product safety and compliance engineers
• Specifiers, architects and procurement teams requiring verified fire-performance data
• Regulators and standards bodies implementing national adoption of CENELEC documents

Related standards

• Other parts of the EN/IEC 60332 series (tests for flame propagation on single cables and other configurations)
• National fire test methods and building codes that reference EN IEC methods

Keywords: EN IEC 60332-3-10:2018/A11:2020, vertical flame spread, bunched wires, cable fire test apparatus, burner positioning, cable fire testing, optical fibre cable fire performance.
